"High quality"
These are high quality stainless steel and we love the non-stick bottoms which make it easier for junior chefs to mix, without spilling! The lids are so useful for storing ingredients until later, keep contents fresh or waiting for dough to firm up/ prove etc. I wouldn't be without them and they're so lightweight, I prefer them to my big, china mixing bowls. We haven't washed the lids in the dishwasher, just incase they warp but the bowls go through and come out looking like new.
